AIR-CARBURETER.

SPECIFICATION forming part of Letters Patent No. "790,025, dated May 16, 1905.

Application led August 13I 1904:. Serial No; 220,651.

T @ZZ whom, it may concern:

Be it known that l, GEORGE L. BENNETT, a citizen of the United States,residing at Chicago, in the county of Cook, State of Illinois, (whose post-oilice address is 1002 West Madison street, Chicago,) have invented a new and useful Improvement in Air-Carbureters, of which the following is a specification.

My invention relates to vapor-generators in which gasolene, naphtha, benzin, or other volatile iiuids are used to produce gas or vapor; and the object of my improvement is to provide an inexpensive portable air-carbur'eter for the use of' dentists, jewelers, and other mechanics in their laboratories in places where they are not otherwise provided with gas. l attain this, object by a mechanism illustrated in the accompanying drawings, in which- Figure 1 is a vertical sectional view showing all parts. Fig. 2 isa top view of the water- V tank and carbureting-chamber with the bell removed. A portion of the top of the chamber is cut away, showing one of the vaporizing-pans and the overflow-vent.

Similarletters referto similar parts throug out both the views.

The cylindricalwater-tank m is constructed of the required capacity, the bottom being placed two inches above the lower rim. The evaporating-chamberiB is made two inches smaller in diameter than thewatertank,hav ing a closed top. The top of the chamber is provided with an openingu'f, having a screwcap, and an outwardly-closing valve e, fixed eccentrically in the top. A tube j, having three or more evaporating-pans 7c, smaller in diameter than the chamber B, are lixed to the tube centrally one above the other at equal' distances apart. The pans l: have overflow-tubes Z iixed in the floors, the top of the overlow-tubes being lower than the' rim ofthe ans and so disposed asto not come opposite to each other. A circular oriiice n is made in the tube between each pan. The top end of the tube carrying the pans 7c is then fixed vertically in the center of the top of the chamber. A circular oriiice is punched in the center of the water-tank floor. The chamber B, having the tube j and pans 7c connected therewith, is placed in the tank, the end of the tube j inserted in the orifice in the iioor of the tank and should protrude about three-fourths of an inch to facilitate connecting the discharging-tube t. The chamber is then adjusted to an e ual distance circumferentially Jfrom the wa of the tank m and soldered fast to the floor of the tank. This will form a one-inch space between the wall of the tank and the chamber. The discharging-tube t' is then lixed to the protrudinx end of the tube j and extended horizontal y beneath the lloor to the outside of tank, then carried vertically to the top of' tank and iitted with a stop-cock 71.-. The cylindrical bellAis made one-half inch smaller in diameter than the tank andprovided with a handle c in the center of the top. An outwardly-closing valve d is lixed eccentrically in the top of the bell. The side wall of the bellA is carried up'above the top about one and one-half inches to form a rim, thus completing the device.

In operation, the space o being partially l iilled with water, the cap f is removed. The liuid to be use d is spilled into the pans k suilicient to lill them. It they overflow, it will fall to the bottom of the chamber and evapof rate Jfrom thence. The cap fis then replaced. y

The bell is inverted and placed telescopically around the chamber in the water where it will iioat. The weight of the bell will compress the air and it will pass down through the valve e and over and around thepans. The iluidused will soon unite with the air and be ready to ilow out through the apertures 'a in the exhaust-tube 7' to the discharge-tube t. A hose can be fixed to the cock h leading to a blowpipe or vulcanizer or such other instrument as may be required, or it may be connected with a Bunsen burner and Welsbach mantle. When the bell has been exhausted, seize the handle and lift it up. The

IOO

Having described my invention and its operation, I do not Wish to confine myself to the specific number of evaporating-pans, since they may be multiplied if faster evaporation is required; nor do I Wish to conline myselr` to generating fuel-gas exclusively, as an esthetic vapors may be generated equally as Well and conducted to an inlialer. I am aware that volatile luids have been evaporated by being spread over large surfaces. Therefore I do not claim the combination broadly; but

What I do claim as my invention, and Wish to secure by Letters Patent, is*

The combination in a carbureting-machine, the superimposed evap orating-pans iXed centrally to a vertical tube, the overlloW-vents iXed eccentrically in Hoor of said pans, the said tube having discharging-ports above each pan, the tube and pans Iixed centrally in a cylindrical chamber, the outwardly-closing valve, and means 'for charging said pans, fixed in the top of said chamber, the (lischarging-tube connected externally with the vertical tube, in combination with a watcrtank and vfloating bell substantially as dcscribed.
